org.apache.qpid.test.framework.BrokerLifecycleAware

BrokerLifecycleAware is an awareness interface implemented by test cases that can run control the life-cycle of the brokers on which they run. Its purpose is to expose additional instrumentation of brokers during testing, that enables tests to use an automated failure mechanism to simulate broker failures, and to re-start failed brokers.

CRC Card
Responsibilities	Collaborations
Indicate whether or not a test case is using an in-vm broker.
Track which in-vm broker is currently in use.
Accept setting of a failure mechanism.	{@link CauseFailure}.

@todo Need to think about how to present the brokers through this interface. Thinking numbering the availablebrokers from 1 will do. Then can kill 1 and assume failing onto 2. Restart 1 and kill 2 and fail back onto 1 again?
